INJECTOR-BURNER SPECIFICATION forming part of Letters Patent N o. 698,553, dated April 29, 1902. Application filed December 14, 1900. Serial No. 39,907. (No model.)

To a/ZZ whom it may concern:

Be it known that I, WILLIAM PLorrs, a citizen of the United States, residing at Whittier, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Injector-Burners, of which the following is a full, clear, and exact description.

This invention relates to an injector-burner for hydrocarbon'fuel which is so constructed that when connected up with the steam-pipe of a furnace for supplying to the burner the necessary steam to injectl the fuel and support the combustion thereof the pressure of the steam Will so regulate the valves through which-the steam and liquid fuel enter that the amount of fuel will be automatically regnlatedby the steam-pressure of .the boilerthat is to say, the burner may be so regulated that it will maintain a given pressure of steam in the boiler by opening or increasing the supply of fuel as the pressure is low- 'ered and reducing or cutting off the supply of fuel as the pressure reaches or exceeds the desired degree.

IThe invention consists in certain novel features of construction and a novel arrangement of the parts, hereinafter fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a conventional representation of a steam-boiler, showing my new burner applied thereto.` Fig. 2 is a front elevation of the burner. Fig. 3 is a vertical section of the burner on the line III Ill, Figs. 2 and 4. Fig. 4 is a plan of the burner.

A represents a steam-boiler, B the steamdome thereof, and C the main steam-pipe.

D represents the combustion-chamber beneath the boiler.

1 designates the casing, which, with the base 2, forms a compartment or chamber 3.

4 indicates an elastic steeldisk which extends horizontally through the entire chamber and just above the floor thereof. Mounted on the disk 4 is a valve-seat 5 of a valve 6, which has a threaded stem 7, provided with a hand-Wheel 8, said stem extending through a bushing 9 in the upper part of the casing 1, as shown. Another valve-seat 10 is mounted on the disk 4 and receives a valve 1l, which has a threaded stem 12 extending upward through the bushing 13 in the upper part of the casing and provided with a handwheel 14. A pipe 15 enters the casing and is connected with the seat 5 of the valve 6, this pipe being for the supply of oil or other hydrocarbon liquid. enters the casing and is connected with the seat 10 of the valve 11. A small hole 17 is made in the valve-seat 10, through which steam may be allowed to enter the narrow space under the disk 4 during operation.

18 indicates a small pipe extending horizontally from the steam-valve seat 10 to the discharge-opening in the casing.

In operation the two regulating-valves 6 and 11 are opened byturning the handwheels 8 and 14, and fuel from the inlet-pipe 15 passes through the `valve-seat 5 Zinto the chamber 3, then to the burner 18a. Steam enters the valve-seat 10 through the inletpipe 16 and passes out through the pipe 18 to the burner, where it is mixed with fuel. A portion of the steam, however, enters behind the diaphragm 4 through the hole 17 and forces the diaphragm away from the walls of casing whenever the pressure of `steam in the boiler becomes excessive. `The Valve-seats being carried by the diaphragm aremoved simultaneously toward the regulating-valves 6 and 11, whereby the supply of fueland steam is reduced or cut o, depending upon the positions of said regulatingl valves.

The varying pressure of the steam actuates the valves, so that the device is self-adjusting. The valves are also subject to the control of the operator, who can readily subject the iiow to whatever pressure he desires. A saving of fuel is thus eected by producing a uniform flow of 'liquid and of` steam, and

the operation requiringless attention of the v firemen a saving of labor is also eifected.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a device of the class described, the combination of a plurality of valves, each having a movable member, and'means having all of said valve members mounted on one side thereof, said means being operated by the A steam-inlet pipe 16 IOO pressure of steam from a boiler to control the How through the valves.

2. In a device of the class described, the combination of a plurality of valves, each havingamovable valve member,and a diaphragm having all of said valve members mounted on one side thereof, said diaphragm being operated by the pressure of steam from a boiler to control the flow through the valves.

3. In a device of the class described, the combination of a steam-supply pipe, a fuelsupply pipe, a diaphragm, a valve having a valve-seat communicating With the steamsupply pipe and mounted upon one side of the diaphragm, a second valve having a valve-seat communicating with the fuel-supplypipe and mounted upon the same side of the diaphragm and means admitting steam to the opposite side ofthe diaphragm.

4t. In a device of the class described, the combination of a casing having a compartment, a steam-supply pipe, a fuel-supply pipe, a diaphragm secured Within the compartment, a valve having a movable member communicating With the fuel-supply pipe and secured to the diaphragm, a second valvehaving a movable member communicating with the fuel-supply pipe and secured on that side of the diaphragm upon which the steam-supplyvalve member is mounted, said movable member of the steam-supply valve being provided with an opening communicating with the other side of the diaphragm to move the valve members simultaneously.

5. In a burner for hydrocarbon liquids, the combination with a compartment of an elastic diaphragm extending through said compartment, a liquid-supply pipe having a valve and a valve-seat, the latter being mounted on said disk, a steam-pipe having a valve and a valve-seat, the latter being mounted on said disk and adapted to admit steam to the space under said disk, valve-stems connected with said valves, and a steam discharge pipe adapted to mingle steam With said fluids, substantially as set forth anddescribed.

6. The combination of a casing,a diaphragm mounted Within the casing and adapted to be moved by steam-pressure, and a plurality of valves also mounted within the casing,each valve having a `movable member secured to the diaphragm.

7. The combination of a casing,a diaphragm mounted Within the casing and adapted to be moved by steam-pressure, a steam-supply valve and a fuel-supply valve both of which are mounted Within the casing, and a movable valve-seat for each of said valves, secured to the diaphragm.
